25 x10 x8 x 4 x25 x50
=25 x 10 x 2 x4 x4 x25 x50
=(25x4) x(25x4) x x ( 50 x 2) x 10
=100 x 100 x 100 x10
=10000000
A = 19,19 x 2525,25
A = 19 x 1,01 x 25 x 101,01
B = 25,25 x 1919,19
B = 25 x 1,01 x 19 x 101,01
Vậy A = B
\(\text{+)}\)
\(A=19,19.2525,25\)
\(A=19.1,01.25.101,01\)
\(\text{+)}\)
\(B=25,25.1919,19\)
\(B=25.1,01.19.101,01\)
\(\Rightarrow A=B\)
\(\dfrac{x-25-124}{2015}\) + \(\dfrac{x-124-2015}{25}\) + \(\dfrac{x-2015-25}{124}\) = 3
\(\dfrac{x-15-124}{2015}\) - 1 + \(\dfrac{x-124-2015}{25}\) - 1 + \(\dfrac{x-2015-25}{124}\) - 1 = 0
\(\dfrac{x-15-124-2015}{2015}\)+\(\dfrac{x-124-2015-25}{25}\)+\(\dfrac{x-2015-25-124}{124}\) = 0
\(\dfrac{x-\left(15+124+2015\right)}{2015}\)+\(\dfrac{x-\left(124+2015+25\right)}{25}\)+\(\dfrac{x-\left(2015+25+124\right)}{124}\) = 0
(\(x\) - 2164).(\(\dfrac{1}{2015}\)+\(\dfrac{1}{25}\)+\(\dfrac{1}{124}\)) = 0
\(x-2164\) = 0
\(x\) = 2164
